Answer:

The correct answer will be- Bacteria were able to utilize the food material in nine containers by producing respective enzymes.

Explanation:

The process of utilization of food material as a source of food depends on the Operon machinery of the Bacteria. The Operons gets activated in the presence of the inducer molecule which leads to the gene expression and the production of the enzymes to digest the food substance.

In the given condition, since the bacterial growth was observed in the nine containers out of ten shows that bacteria expressed the genes and produces enzymes to digest the substance in nine plates only and showed growth.

Thus, Bacteria were able to utilize the food material in nine containers by producing respective enzymes is the correct answer.

Which of these correctly shows ecological succession in a lava field?
larisa [96]

The ecological succession that occurs in a lava field is as follows:

  • Moss and lichen arrive by birds to barren lava field.
  • Soil is created.
  • Fountain grass grows.
  • Monkeypod trees grow.

<h3>What is ecological succession?</h3>

Ecological succession refers to the series of changes that occur in a habitat gradually with new species replacing existing species or a barren habitat until the environment becomes more complex.

A lava field is a barren field where there are no species

The ecological succession that occurs in a lava field is as follows:

Moss and lichen arrive by birds to barren lava field; Soil is created; Fountain grass grows; Monkeypod trees grow.

There is an algal bloom in a lake in a populated area. As the leading scientist for the water department, what is the most impor
tatuchka [14]
The best option is D. Based on scientific evidence about algal bloom, it would be best to evacuate all humans from the area around the lake. Algal bloom is caused by excess nutrients in the lake. This occurrence is linked to the death of fishes, plants, mammals and birds. Also. it has been said to cause human illnesses. Thus, to avoid this, it would be best to stay away from the lake with algal bloom.

Alona [7]

Answer:

Your question is incomplete but supposing that the mother is a recessive allele and the father is dominant, we deduce that his daughter could have curly hair or else wavy hair that would be a combination of the two since both parents can incompletely dominate

Explanation:

The chances that your child has curly hair is 50%, that is, it would be the most likely, and also the genotype that you would need for this child to have curly hair would be: CC with CS or CC with CC

A specific example of a light year is used in space exploration
Pani-rosa [81]
Light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in a vacuum in one year.

While there is no authoritative decision on which year is used, the International Astronomical Union (IAU) recommends the Julian year.

A light-year is equal to 9,460,730,472,580.8 km (about 9.461 Pm; 5,878,625,373,183.61 statute miles; about 63,240 astronomical units or about 0.3066 parsecs.

The exact length of the light-year depends on the length of the reference year used in the calculation, and there is no wide consensus on the reference to be used.

The figures above are based on a reference year of exactly 365.25 days (each of exactly 86,400 SI seconds).

A few examples of distances for light to travel are: Reflected sunlight from the Moon's surface takes 1.3 seconds to travel the 4.04 × 10-8 light years to Earth.

It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).

The most distant space probe, Voyager 1, was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004.

It took Voyager 27 years to cover that distance.

The nearest known star (other than the Sun), Proxima Centauri is 4.22 light years away.

The center of our galaxy, the Milky Way, is about 26,000 light years away.
